Abstract (en)
[origin: EP2113927A1] The winding tape has a plano-convex cross sectional form defined by a curved upper limiting line and a lower limiting line, where the tape is made of PTFE. The tape contains a lubricant or slip agent conductive filler material such as graphite, soot or metal oxide, where surface resistance of the tape is 10 Ohm/square millimeter to 10 megaohm/ square millimeter. Thickness of the tape is 20 to 200 micrometers, and breadth of the tape is around 10 to 30 millimeters. An independent claim is also included for a method for producing an unsintered winding tape.
